That's about as "tight" as you could hope for, but, as I said still too cool (blue). A quick grayscale calibration targeting 6500K, required only an adjustment of the Blue Gain to 403 from 408 (leaving all other Gain and Offsets at default) This spread out the color temperature a bit, and a little more work with the Offset would have tightened things up again, but these numbers are
Those are the settings I used for all photos from
movies in the Image Quality section (unless otherwise noted).
The Home Theater mode - more suitable for TV/HDTV/Sports, should be around 8000K, but I measured 8676K at 100IRE, not far off. I did not measure the lower IRE's nor attempt to calibrate this mode.
